My invention is a slug ejector for coin machines, adapted to eitherdischarge or to return so-called slugs or other devices which a personmay attempt to ass for a coin.

An object of my invention is theconstruction of a slu ejector for usewith coin con trolled machlnes adapted to throw out coins which havemagnetic properties, those having smooth faces and rims and those havingholes in the center.

Another object of my invention is to construct a slug ejector which willproperly handle a legitimate coin to operate the'coin controlled machineand will return the slugs or like constructions to the operator of themachine.

A further object of my invention is a slug ejector in which coins havingmagnetic properties are discharged from the chute in which they areinserted and have means by which slugs having magnetic properties areforced into engagement with the magnet and thereby guided into adischarge chute for mag netic slugs.

A still further object is the construction of a slidable type of coinblock containing a pocket for coins and having means in said block togrip and hold coins by the head or rim around the edge such anismfailing to hol smooti surface slugs and allowing these to drop in thetravel of the block, into a slug ejecting chute; The machine is providedwith 'means" for disengaging the coin holding device and allowing F5coins to drop in a coin chute.

Slugs which have a bead on the edge and a hole in the center aredisengaged from the holding device after passage of the slug chute andare retained by a stopping device engaging the central aperture, therebylimiting the movementof the coin block so that it is not positioned overthe coin chute. On the return movement the gripping device fails toengage such slug with a rim and a 5 hole as these have been slightly droped and such slugs are moved in the slug c ute and discharged.

Another object of my invention is in providin a delay "action or aslight stop when 0 the sliding coin block is positioned over the uppingmech 7-7 of Fig. 5 in the direction of the arrows;

ever, has in addition means to institute the A positive ejection of aslug and means to prevent insertion of coins or slugs in the coin 1block before same is properly positioned.

Other detail features will be apparent from the description.

The stationary housing for the slug ejector mechanism is constructedsubstantially as follows:

The housing is designated generally by the numeral 1, being preferablyin two longitudinal halves formed substantially the same and attachedtogether by screws or the like. The upper portion 2 contains an insertcoin chute 3, this chute havingan inclined passage 4 followed by asubstantially vertical drop passage 5. A permanent magnet 6 is mountedon a lug 7 and a chute 8 for slugs having magnetic properties ispositioned below the magnet, discharging at the front of the machine. Aguideway designated generally by the numeral 9 extends lengthwise of thehousing or block and preferably has a plug 10 formin a closure for theforward end, this plug eing attached by a set screw 11 or the like. I

A slug chute 12 is formed in the housing back of the coin drop passage 5and still further rearwardly. a coin chute 13 is formed. An insert plate14 preferably of hard metal is positioned below the coin drop passage 5and extends upwardly above the base 15 of the guideway 9. A wear plate16 is inserted adjacent the slug chute and its upper surface is inalinement with the base 15 of the guideway. One side of the guideway isprovided with a lon itudinal passage 17 and has a slot 18 exten ing partof the length of the housing and extending into the passage 17. Theupper portion of the guideway has bearing surfaces 19 for the coin blockas hereunder described and with a roof section 20 located above the topof any coin which might be inserted in the machine.

The side portions 21 of the guideway are to accommodate holding orretaining devices for the coins as hereunder described. The

housin is supported by lugs 22 or the like at the ase which may besecured to a coin controlled machine of any suitable type. The sides ofthehousing are provided with forward cam surfaces 23 and rearward camsurfaces 24, these being preferably hard metal inserts into the sideportions 21 of the guideway for controlling the operation of thesuspending fingers or dogs for'coins as hereunder set forth in detail. A

A recess 25 is formed in one of the housmg sections and a lever 26 isivoted on a vertical pin 27. This lever as a small roller 28 at one endand a compression spring 29 positioned between such end of the leverhaving the roller and the side of the housing. A slidable pin 30 isfitted through an aperture 31 in the lever, this pin being normallypressed towards the guideway by the leaf spring slot 32.

The housing sections have a socket 33 formed in each half and aslugejector pin 34 extends downwardly-into the guideway.

psection 45 on one side.

32, and passing through the This pin has a head 35 resting in the bottomin each half of the housing and having a compression spring normallyforcing same into the coin passage5 as shown in Fig. 5. The pin has adepending arm 41 go engage the coin block as hereunder set orth.

The coin block is designated generally by the numeral 42 and has a websection 43, an upper flangesection 44 and a lower flange The block has aslight incline 46 at the rearward end, 47 at the forward end and 48 and49 at each end of the coin pocket 50 which extend vertically through thecoin block. The web of the block is provided with a longitudinal groove51 at the bottom, this groove sliding over the insert plate 14. A pairof lateral .sage and have a pair of dogs or fingers 53 mounted therein,these being swivelled on pins 54. The gripping ends 55 of the dogsextend into the coin pocket 50, the outer ends 56 extend into the sideportions 21 of the guideway and are positioned to engage the stationarycams 23 and 24. The lower flange 45 is provided with a screw threadedhole 57 for a pin as hereunder set forth.

The operating mechanism for the slug ejector is constructedsubstantially as follows, having reference particularly to Figs. 1, 2and 4:

This illustrates the pausing motion device. Anoperating arm 58is-mounted on a bolt 59 which is threaded into a lug 60 extendinglaterally from one side of the housing. A coiled spring 61 securedrespectively to the operating arm and to the lug is normallyextendsthrough this U shaped slot throughthe longitudinal slot 18 and is screwthreaded into the hole 57 in the flange 45 of the coin block.

The manner of operation of my slug ejector is substantially as follows:

Fresuming firstthat a slug having magnetic properties is inserted in thecoin chute 3, this is guided by the inclined portion of the passage 4'sothat the edge'of the slug is drawn against the magnet 6 substantially atthe pole pieces where the magnetic flux is strongest. The magnet thusattracts the slug and causes it to follow the path 8 for slugs havingmagnetic properties. It does not matter whether the slug is gentlyplaced in the coin chute or vigorously forced therein as in both casesthe slug is sure to be thrown against the magnet and brought into actualcontact with same.

If a legitimate coin is inserted in the coin chute this coin having nomagnetic properties follows the inclined path 4 and drops verticallyinto the lower drop portion 5 of the passage and if the coin blockshould be in a rearward position the coin is retained elevated by meansof 'thepin 38 which proj ects into the coin drop passage 5. However,when the coin block is in its normal stationary or initial position asshown in Fig. 3,

the coin drops into the coin pocket of the block, the lower edge of thecoin resting on the upper edge of the insert plate 14 as indicated inFigs. 3 and 4. In this position the cams 23 hold the dogs 53 so that thegrippingends 55 are moved out of contact with the coin. When theoperating arm;58 is drawn forward at its upper end the motion istransferred through the pin 66 connected to the flange 45 to the blockand slides the block lengthwise of the housing, as the pin slidesupwardly in the rearward slots 64 until it is positioned in theadjoining slot.

During the slight motion of the lever the coin block is stationary untilthe pin 66 enters the forward slot 63' when the motion is continued. Thecams 24 on the side of the housing for opening the suspending dogs arepositioned to open such dogs when the coin is slightly past the wearinsert plate 16. The coin is then freed and drops on the base surface 15of the guideway and is shoved into the coin chute 13, thereby followingsuch chute into any coin controlled machine.

Presuming a coin having a smooth edge without any bead and without anycentral perforation or the like is utilized, this coin beingnon-magnetic, it drops in the same manner as a legitimate coin throughthe coin chute into the coin ocket of the coin block but as the suspenring dogs do not grip such coin, there being no bead, it is carried bythe block until the slug rolls ofi the upper edge of the insert plate14. Just at this edge the upper edge of the slug comes into contact withthe pin 34 pressed downwardly by the spring 37, being forcibly thrustdownwardly into the slug chute 12. At this particular time the pin 66 istraversing the joined section of the U-shaped slot and the block is heldstationary for the moment. Therefore this gives suflicient time, nomatter how quickly the operating arm is worked and the coin block slid,for the slug to drop clear of the coin block into the slug chute, asthere is always this pause or positive stop in the movement of the coinblock.

Presuming a slug non-magnetic and having a central aperture with a beador rim on the edge is utilized, this falls through the coin chute intothe coin pocket of the coin block inthe manner above describedand thegripping dogs engage such slug by the rim carrying it .suspended in thesame manner as a legitimate coin, over the coin chute 12 V in thebackward movement of the coin block. This slug is however, dropped bythe dogs engaging the cam 24 as above described so that it rests on theup er surface of the insert 16 on a level wit the base 15 of theguideway.

The movement, of the coin block rearwardly engages the roller 28 on thelever 26, swinging 'such lever from the position shown in Figs. 7 and 8to that shown in Fig. 9 and in such action the pin 30 is thrust by meansof the spring 32 into the central aperture of a slug as shown in Fig. 9.When a legitimate coin is used however, the spring 32 gives and allowsthe coin to be thrust further into the coin chute 13. When the pin 30 isengaging a slug this blocks the movement of the machine preventing theblock from being moved back any further. The spring 61 will then drawthe block forwardly unless the person operating same voluntarily doesthis and in such action the coin pocket 50 rolls the slug on the upperedge of the insert 16, this being released from the pin 30 by the spring29 forcing the lever back into its original position of Figs..7 and 8.Such slug therefore drops into the slug chute 12-and is discharged.

It will thus been seen that with my slug ejector I have a device whichwill throw out slugs having magnetic properties no matter whether theyhave beads on the edge or not, as these do not get into the machine.Slugs which are smooth surfaced are also readily ejected as they are notretained suspended by the holding mechanism. Slugs which have a centralaperture and also 'have a beaded rim are also rejected, such slugs beingretained by the device engaging the central aperture and preventingtheir being positioned over the coin chute and causing their ejectionthrough the slug chute. Legitimate coins however, even if the bead isvery much worn are carried through and passed into the coin chute.However, should the bead be entirely eliminated from such coins theyferent prices, or the like, such as set forth.
